Suppose that you would like to develop a method of finding students who are likely to have a low college GPA, based on any of the other numerical variables in the data set. Use linear regression to develop such a method, and interpret your results.

Background on the data set

Each semester in all of the Introductory Statistics sections at the University
of Puget Sound, a survey is given to the students during the first week of class.
The survey is voluntary and is used as an example data set throughout the class.

The data set given here is a compilation of much of the data collected in
the period from the Fall 2002 semester through the Spring 2008 semester.
Values that have been
determined to be incorrect (such as 8-foot tall students) have been removed
from this data set.
